SPECIFICATION forming part of Letters Patent No. 470,453, dated March 8, 1892.

Application filed February 11, 1884.

To a whom it may concern.-

Be it known that I, ANDREW STARK, a citizen of the United States, residing at Chicago, in the county of Cook, State of Illinois, have invented certain new and useful Improvements in Grain-Binders, of which the following specification contains a full and accurate description, from which any one familiar with the art can make and use the same.

This invention is designed to provide in a grain-binder improved mechanism for forming the knot to secure a cord band about the sheaf.

My invention consists in the arrangement and combination of devices hereinafter described, and set forth in the claims.

Figure 1 is an inside elevation of the binderframe. Fig. 2 is arear elevation of the same. Fig. 3 is a rear elevation, and Fig. i is a front elevation, of the binder-head. Fig. 5 is a plan of the binder-head. Fig. 6 isa'rear elevation of the knotter and stripper in their relative positions. Fig. 7 is a partially sectional elevation of the knotter. Fig.8 is a partially sectional plan of the same, section being taken at as y, Fig. 7. Fig. 9 is an elevation of the tucker andstripper. Fig. 10 is a plan of the same. Fig. 11 is a plan, and Fig. 12 is avertical section, of the cord cutting and holding devices. Fig. 13 is a detail view ofthe cordgrip therein. Fig. 14 shows the knotter in co-operation with the needle-arm and compressor, illustrating successive positions of the latter. Figs. 15, 16, 17, and 18 are plans showing details of the knotter and tucker and stripper and cord holder and cutter in successive stages of the knot. Fig. 19 is a vertical section of the cord cutter and holder combined with an outside elevation of the knotter-actuating wheel and its lever-arm.

cord cutter and holder, the secondto discharge the bundle, and on the inner face of the knotter-actuating wheel the gear-segment 3, the interior rim gear-segment 4, and separated therefrom, but in effect as a part thereof, the radial tooth 5, the hub 6, having the two radial projections 7 and 8, and on the outer edge of the knotter-actuating wheel the radial projection 9; second, vertically journaled in the bracket A and therefore parallel to the vertical plane of the needle, the knot-tyer F comprises the following parts: the tubular shaft 10, terminating in the lower horizontal fixed jaw 11, the plunger 12, linked at the lower end to the bell-crank lever 13, which constitutes the upper movable jaw, the spiral spring 14, forcing upward the plunger 12 and so tending to hold the jaws closed, the cap-nut 15 on the upper end of the plunger 12, against which the spring 14 reacts, the bevel-pinion 16, rigid with the shaft 10, having the delay-surface 17, and the lever 19, pivoted upon the head of the plunger 12; third, the tucker and stripper G, consisting of the mutilated pinion 21, the mutilation consisting in two delay-surfaces separating the segment 21 from the isolated cog-space 21 (see Fig. 9,) rigid with and on the outer end of its shaft 22, having horizontal bearings through the bracket A the bevel-gear 23 on the inner end of the shaft 22, and meshing with it the bevel-gear 24 on the upper end of the vertical shaft 25, having bearings in the bracket A and having on the lower end, which extends below the edge of the bracket A the stripper 26, shaped as shown; fourth, the cord cutter and bolder H, consisting of the horizontal disk 2'7, which is but an expansion of or is rigidly secured to, and in any event is rigid with, the downward projection 28 of s on the bracket A so as to rest its free end the bracket A in which, as stated, the knot tyer is journaled, so that the axis of said disk is fixed with respect to the axis of said knottyer; upon the upper surface of this disk, near the circumference, the cord-clamp, which is an eccentric cam 29, having as its axis the stud 30, which is substantially parallel to the knottyer axis and about which is coiled the spring 31, having one end 32 engaged behindthe offset 33 upon the upper surface of the eccentric and tending to hold the serrated edge 34 of the eccentric in the position shown in Fig.

11; the cup 35, which consists of the flat bottom 35% and the side or flange 352, projecting at right angles to the bottom, and which, fitting closely under and around the disk 27 and concentrically secured to and adapted to revolve around it by means of the screwstud. 36, has the notches 37 through its sides andthe cars 38 between the notches, as shown in Fig. 11, said cord-holder cup being horizontally extended transversely to the vertical plane of the needle, and its center and axis being nearly coincident with the said plane of the needle it extends on both sides of that plane, its diameter, moreover, being sufficient to cause it to extend beyond the plane of the axis of the kn'ot-tyer; the slack-loop hook 40, pivoted at 41 on the bracket A with its angle reachingto the circumference of the knotter-actuatin g wheel C and provided with a shoulder 42, adapted to be engaged by the projection 9, and with a spring 42%;, tending to throw it forward, while the point 43 is of suchlength as to strike into the circle of the cutter-cap, as shown in Figs. 15, 16, 17, and 18, and having theset-off 43. for the purpose hereinafter described; and, lastly, the cutters 39, i

set obliquely into the edges of the notches 37.

K isthe binding-platform.

L is the breast-plate, secured to the lower edge-of the frame A and having the slot I, through which the needle may pass and carry the cord to the binderhead. The binder stands at rest in the position shown in Figs. 1,2, 3,. and 4. The knotters relation to the tucker and stripper and cord holder and cutter in that position is shown inFigs. 5, 7, and 15, the needle being below the platform, the endof the cord being held by the cord-holder H, the cord being therein looped back around the hook 40, thence extending out through a notch 37 in the flange 35% across, above, and lying upon the closed jaw of the knot-tyer F over theheel of the stripper, around which it is drawn down in front of the accumulating bundle. As the binder-driving wheel B begins tomove the knotter-actuating Wheel 0 revolves in the direction shown by the arrow in Fig.2. As the needle-arm carrying the cord rises through the platform and divides the bundle. from the flowing grain the link D drawsthe com pressor-arm also up on the other side of the bundle, and the two arms thus continue to approach and compress the bundle. between them as the driving-wheel contin ues to revolve. When the needle has passed through the slot I in the breast-plate, it lays the cord again across the heel of the tucker and stripper G alongside the part already drawn over it, the cord now completely encircling the bundle. At this point as the knotter-actuating wheel 0 continues its revolutions the single tooth 5 engages in the single notch 21 of the pinion 21 and turns the tucker and stripper G from the position shown in Fig. 15 toward that shown in Fig. 16, and both parts of the cord, being cast off the heel and falling under the point of the tucker and stripper G, are by its further partial revolution tucked within the are described by the knotter-bill, so that the two ends of the bundle-encircling cord lie together in the angle of the knotter-bill with its shaft, which at this point begins to be revolved by engagement of the beveled gear-segment 3 with the bevel-pinion 16 and comes into the position shown in Fig. 16, the point of the knotter-bill passing close over the point of the tucker and stripper. Up to this stage the point 43 of the slack-hook 40 has stood down within the circle of the flange 352 of the cord holder and cutter H- and has detained a loop of the bindingcord, as illustrated in Fig. 15, the said cord running from the clamp 29 back around the ,hook 40 and thence forward through one of the notches 37 and around the bundle. The l needle at this instant stands alongside of the 1 slack-hook 40 in the highest (dotted) position, 5 (illustrated in Fig. 14 and seen also in plan view in Fig. 16,) the cord running from the bundle between the slack-hook and theneedie and entering the eye of the latter. 1 this stage the projectiont) on the knotter-actuating wheel engages the shoulder 42 of the i slack hook 40, and, lifting the hook to-the po- {sition shown in Fig. 14, allows the loop'to run 1 out. Said proj cation 9, having passed the said shoulder and allowed the slack-hook to drop off its point,,descends and passesbetween the cord and the needle, and in so descendingits set-off or shoulder 43%- engages the cord and depresses it into the notch 37 of the flange 35%, from whichthe former slack loop has escaped, as described. The knotter-bill, continuing its revolution, takes up the released slack cord around itself, completing about three-quarters of its revolution before the projection 7 on the hub of the knotter-actuating wheel depresses the lever 19 and the plunger 12 in the knotter' shaft or stem and opens the knotterjaw, which, still continuing to revolve, standing open, receives the two ends of the cord-,and immediately after, the projection 7 having now passed beyond the end of thelever 19, the plunger 12 is returned and the action of the spiral spring 14 closes the jaws and grasps thecord ends firmly. At this point the radial arm 1 is in engagement with an car 38 of the cord cutter and holder, and as the knotter-actuating Wheel continues to revolve the cord holder and cutter is revolved by the arm 1 in the same direction. as the knot-tyer, moving the notch in which the cord lies and IIR which the tyer is located.

thereby the cord lying therein transversely to the vertical plane of the needle toward that side of the vertical plane of the needle on This causes, first, that the eccentric clamp 29 releases the end of the band, which up to that point has been held between its serrated edge 34 and the inher edge of the flange of the cord-holder cup 35, and the cord end thus escapes through the notch; second, the cutter and holder continuing to be revolved, this movement draws the other end of the cord, which also lies in the notch 37, between the serrated edge of the eccentric, whose eccentricity causes it to act as a wedge and hold the cord the tighter asit is more tightly drawn by the now retreating needle; third, the cutter and holder cup 35,

still revolving, has at this point brought the knife 39 against and now cuts off the cord, and, passing a little farther, stands in the po sition shown in Fig. 18, at which point the arm I has cleared the car 38, and the cutter and holder stands at rest in theinitial position. During the latter part of this movement of the cutter the gear-segment 4 has been engaged in the unmntilated segment 21 of the pinion 21 and through the bevel-gear 23 has been rotating the tucker and stripper G, which when the cutting is completed stands in the position shown in Fig. 18 with its point under the closed jaws of the knotter-bill behind the encircling loop of the knot. As it continues to revolve it casts the loop off over the points of the closed bill, leaving the ends still held in the jaws. The weight of the bundle will immediately draw the knot tight. At this-point the projection 8 on the hub 6 of the knotter-actuatin g wheel 0 depresses the plunger 12 and releases the ends of the cord. The stripper continuing its revolution, the heel passes backward under the point of the retreating needle, so that the cord is laid over it, as shown in Fig. 15. The knotter-actuating wheel continuing to revolve, the needle and compressor descend, the discharger 2 reaches the bundle and drives it out over the platform, continuing a little farther on, and comes to rest in the initial position.

The relation of the needle-arm D and the compressor D and the connecting-link D and their respective pivotal points and points of connection are such that in the initial positionX Y of the needle and compressor both are below the platform. While the needle advances to X the compressor recedes to Y. While the needle farther advances to X the compressor has recovered its retrogression and advances to Y at the level of the platform. At this point the needle has effected the division of the bundle from the flowing grain, and both needle and compressor now advance toward each other above the platform, compressing the bundle between them until they reach the highest position at X Y The latter part of this motion and the immediately following stage-the receding of both from that position are accomplished of the motion the eye of the needle is carrying the cord by the knotting devices, so that am ple motion is allowed to the knotter-actuating wheel 0 to effect the entire knotting process, while but little change takes place in the posit-ion of the needle and compressor; but after this point is passed, the knot being tied and the bundle ready to be discharged, the wristpin 12 being now well past the center, g1ves a more rapid motion to the needle, Wl110h 1s transmitted to the compressor, which. recedes to Y while the needle recedes and descends to X leaving a clear space between the bundle from which it has receded and the flowing ram.
